What to do about calls from 314 numbers
Before you call back
- Medical & prescriptions is the top named complaint here. Don't confirm your Medicare or insurance number to a caller. Medicare won't cold-call you to sell braces, test kits or plans. Read about Medicare scam calls.
- Look up the full number above. A missed call from 314 with no voicemail is usually a robocall; anyone who needs you will leave a message.
- If it looks like a neighbor's number, it may be spoofed. See calls from your own area code.
- Block repeat callers: iPhone, Android, or your carrier's free filter (Verizon, AT&T, T-Mobile).
Report it in Missouri
- Unwanted sales calls and robocalls: donotcall.gov (FTC). Scams and fraud: ReportFraud.ftc.gov.
- Spoofing, texts and call-blocking problems: FCC consumer complaints.
- State complaints: Missouri Attorney General.
- Missouri is one of the states that maintains its own Do Not Call registry alongside the federal National Do Not Call Registry, so telemarketers calling Missouri numbers are expected to check both lists. Registering on the federal list at donotcall.gov is free and never expires; the state list is administered separately and may have its own registration process and renewal period.
